Here's an Opportunity - Chapter 140: Order of Operations (2)

Xiang Yu was perfectly content with his mediocre life on Earth—average job, average apartment, average everything. That is, until he woke up in the legendary World of Cultivation, where martial artists fly through the skies and immortals battle over ancient treasures.There's just one problem: Xiang Yu wants absolutely NONE of that action.Armed with only his wits and a peculiar system that doubles his exp every 24 hours, Xiang Yu has one goal: become powerful enough to live in peace without getting involved in those ridiculous “protagonist” situations. No ancient tombs. No tournament arcs. And for heaven's sake, stay FAR away from anyone named Chen Mo, Lin Feng, or Li Yao—those names practically scream “main character who will drag me into deadly situations!”Starting with strength stats so pathetic he can barely lift a cultivation manual, Xiang Yu must somehow survive long enough for his exponential growth to matter. After all, doubling zero cultivation talent still equals zero... at first.Follow Xiang Yu on his hilarious journey from zero to hero as he desperately tries to stay invisible while his power skyrockets beyond control! Watch as he dodges cultivation tournaments, avoids suspicious elders bearing gifts, and runs the other way whenever someone mentions “ancient inheritance” or “chosen one.”Join the adventure of the most reluctant cultivator in history whose only wish is peace and quiet, but whose exponential growth makes him the most terrifying force this cultivation world has ever seen!

Coincidentally, indoorsy-guy Zhang Yang went to the cultivation world, being the lowest level of zombie. By using a manual book named: “ Tai Yin Refining Figures”, Zhang Yang find his own way to success and leaves a “If a zombie knows how to use a manual, nobody can stop it “ legend in the world.
